Nope dude, that's incorrect. x and y are wrong. Try forming a real-valued denominator and then check again what x and y are.

i do not get it ? A complex number has a Real part and an Imaginary part. The idea is to breakdown the expression in the form x+iy so i do not understand why you are talking of real valued denominator. Kindly expound by looking at the problem and check where i went wrong.

Solve the complex analysis problem

Suppose z=1/(a+i*b)
Then z not equal to 1/a + i*1/b
Why? Basic fraction calculus. You cannot "split up" a fraction among its denominator, which is what you're intending. You can split it up among the nominator though, so you should make the denominator real-valued by expanding with its complex conjugate, that is
so your final expression would be

If you don't understand the above, my advice would be to real a bit about basics of complex numbers on wikipedia (no offense)
